Honestly, hotels are the one place where I think parking should be free (included in the price, anyway).

I stay there when I'm traveling. There's a decent chance it's either a road trip or I'm flying somewhere and probably renting a car to get around. I don't make a habit of staying at hotels near my home.

There's a bunch of places where you go in your own city, those make more sense to have paid parking because you could more reasonably use public transit or walk.
